There is no cut-out wind speed. The e160i, e230i, e300i, e400n are designed to produce full power in any wind above 12m/s.
The e230i, e300i and e400n models are fitted with a patented pitch control. Blade pitch control is the system which monitors and adjusts the inclination angle of the blades and thus controls the rotation speed of the blades. At lower wind speeds, the pitching system leads to an acceleration of the hub rotation speed, while at higher speeds, blade pitch control reduces the wind load on the blades and structure of the turbine.
